Power Integrations Launches New SCALE-iFlex LT NTC IGBT/SiC Module Gate Driver with Temperature Reading

SCALE-2 technology improves current sharing capability of popular 100mmx140mm IGBT and SiC half-bridge power modules by 20%

德国纽伦堡，PCIM 2023 – 2023年5月9日讯 – 深耕于中高压逆变器应用门极驱动器技术领域的知名公司Power Integrations 今日推出SCALE-iFlex™ LT NTC系列IGBT/SiC模块门极驱动器 。新款门极驱动器适配于流行的100mmx140mm IGBT半桥模块，例如Mitsubishi LV100 和 Infineon XHP 2，以及耐压在2300V以内的碳化硅(SiC)衍生模块。SCALE-iFlex LT NTC驱动器可提供负温度系数(NTC)数据，也即对功率模块进行隔离式温度检测，从而实现变换器系统的精确温升管理。这对于采用多个功率模块并联的系统而言尤其重要，可确保均流精确性并显著提高整体系统可靠性。

Comments Thorsten Schmidt, product marketing manager at Power Integrations : “Designers using SCALE-iFlex drivers in renewable energy and rail transit systems are already benefiting from improved system performance; the SCALE-iFlex solution handles paralleling of modules in a very expert way, making it possible to eliminate one of five modules without loss of performance or current derating. Adding isolated NTC outputs reduces hardware complexity, especially cables and connectors, and helps improve system observability and overall performance.”

基于 Power Integrations成熟可靠的SCALE™-2技术，SCALE-iFlex LT门极驱动器提高了均流精度 ，从而将多并联模块的载流能力提高了20%，使用户能够显著提高其变换器堆栈的半导体利用率。之所以能够做到这一点，是因为每个2SMLT0220D MAG（模块适配门极驱动器）单元的局部控制可确保精确控制和开关，从而实现出色的均流。此外，还采用高级有源钳位(AAC)来提供精确的过压保护。

To further save space, a single 2SILT1200T insulation main control board (IMC) unit can connect up to four MAG-driven power modules in parallel, and due to its compact size, the unit can also be mounted on the power module . The gate driver fully complies with IEC 61000-4-x (EMI), IEC-60068-2-x (environment) and IEC-60068-2-x (mechanical) standards, and can be fully tested by low voltage, high voltage and thermal cycles, thus reducing the designer's development time by 12 to 18 months. The driver integrates comprehensive protection features, and an optional conformal coating process can also be added.
